Kylie White scored what would end up being the game-winning goal in the 37th minute on a cross into the box from Skylar Baker.
Avila ruined the shutout for the Wildcats in the 86th minute as Danielle Price finished a goal after receiving a ball from Tracie Geile.
The Wildcats outshot Avila 17-7 overall and 10-4 on goal. Goalkeeper Maggie Dupes made three saves in the contest.
“The girls came out early and set a great pace,” said head coach Nate Houser. “They were able to keep the ball and create some great chances and finish them. I thought we got great effort from our new players and great leadership from our returners.”
Baker (12-3-1, 6-1-1 HAAC) will face Graceland University in the 2011 HAAC Championship game (10-5-3, 5-1-1 HAAC) on Nov. 12 at 5 p.m. from Liston Stadium.
